将数组拆分为单独的数组

Question

I have an array $products which contains a non-fixed number of elements.

I need to split this array into 3 individual arrays. The first two arrays should contain an equal number of elements and the last array may contain less.

So for example if $products contains 16 elements, the output should be:

• Array 1 contains: 6 elements
• Array 2 contains: 6 elements
• Array 3 contains: 4 elements

In the event that there are less than 3 elements in $products , then the relevant arrays need to just return empty.

How can I do this? I tried using array_chunk() but doesn't quite do what I want.

$distributed = array_chunk($products, 3, true);

Answer 1

刚刚找到答案：

$distributed = array_chunk($products, (int)ceil(count($products)/3), true);
